Ok - thought I post an update on how well this thread has inspired me, (and to keep it at the top for others to see)
I first posted on 20 August, recognising all the bad habits in everything 01gt4.6 said.

I STOPPED making excuses that day.

I now love the swimming and walking I do, I look forward to the heat in my muscles overnight and the next day.

My clothes are literally hanging off me, I've got 1 more notch on my belt left to go, then I'll need a new one. People are starting to comment on me looking slimmer. I feel more full of energy, as I've stopped eating junk. And the things I thought I'd miss - I don't.
